Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12950, here are decompositions:
- 31 + 12919 = 12950
- 43 + 12907 = 12950
- 61 + 12889 = 12950
- 97 + 12853 = 12950
- 109 + 12841 = 12950
- 127 + 12823 = 12950
- 151 + 12799 = 12950
- 193 + 12757 = 12950
Showing the first eight; more decompositions exist.
